Objective To explore the prenatal indications and pregnant outcome of balanced transloca-tion at amniocentesis, so as to provide scientific guidelines of prenatal diagnosis for local pregnant women. Methods Retrospective review was made on 76 cases of balanced translocation at amniocentesis from 2011 to 2015 at our hospital. Results In 76 cases, 38 cases were aged pregnancy prenatally, 20 cases carriers, 9 cas-es abnormal serum screening , 5 cases with previous abnormal births , 2 cases with abnormal ultrasound findings and 2 cases with other problems. Conclusion Balanced translocation concomitant aneuploidy , de novo X-auto-some translocation or de novo complex chromosome rearrangements can cause fetal abnormalities on prenatal di-agnosis. The results of ultrasound, FISH and array-CGH could provide for de novo simple translocation at amnio-centesis.

[ ABSTRACT] Chemokines and their receptors have been implicated mostly in tumor progression and metastasis. Atypical chemokine receptors ( ACKRs) comprise a group of 7-transmembrane domain proteins structurally similar to G pro-tein-coupled receptors.However, ACKRs do not induce classical signaling via the typical G protein-mediated pathways. ACKRs efficiently internalize the cognate chemokine ligands and act as scavengers instead.ACJRs are composed of at least 3 members of chemokine receptors: Duffy antigen receptor for chemokines ( DARC, also known as ACKR1 ) , D6 ( also known as ACKR2) and ChemoCentryx chemokine receptor (CCX-CKR, also known as ACKR4).These receptors bind to and/or internalize their chemoattractant ligands without activating signal transduction cascades leading to cell migration.In this review, we summarize the recent progress regarding the roles of ACKRs in the progression and metastasis of tumor.

Based on the physical characteristic of ultrasound, the images of body tissues can be obtained through ultrasonic medical technology, which is another flourishing cross-linked branch of BME after X ray technology. Being non-invasive, painless and reusable, ultrasonic medical technology is suitable for the examination and treatment of the soft tissue. This paper introduces such of ultrasonic technology as its basic principle, developing prospect and application to clinical medicine.

【Objective】 To investigate the effect of Kaixin Capsule (KC) on gene expression of myocardial immune inflammatory factor in dogs after resuscitation and to search for an effective way to counteract the progress of systemic inflammatory response syndrome (SIRS) after cardiopulmonary resuscitation. 【Methods】 Fifteen hybrid dogs were randomly divided into three groups, 5 dogs each: pseudo-operation group (group A), model group (group B) and KC group (group C). The dog model of cardiac arrest and resuscitation was established; the dogs were executed and the heart was isolated 180 min after the recovery of autonomic circulation. Myocardial total RNA was extracted and the mRNA expression of objective gene was detected by reverse transcription polymerase chain reaction (RT-PCR). 【Results】 mRNA expression of Toll-like receptor (TLR_4) and tumor necrosis factor ?(TNF-?) in group B differed from that ingroup A (P

In this study, nattokinase gene was amplified by PCR using bacillus subtilis chromosomal DNA as template and cloned into expressed vector pBV220. After transforming recombinant plasmid into E.coli HB101, the recombinant strain was yielded. It was proved that expression products was secretive and expression protein was 12% of total cell protein by SDS-PAGE. Optimum culture time and inducing time was determined as 6h and 5h respectively. The plasmid stability studies showed that recombinant plasmid has excellent segregational stability but the structural stability was not good in the host cell.

Objective To explore the relationship between the endemic arsenism and the liver,renal damage.Methods Some permanent residents were selected as investigated subjects who lived at 3 villages in Datong in Shanxi Province,an arseniasis-endemic areas,These objects were divided into arsenic poisoning and control group on the basis of Diagnosis Standard for Endemic Arsenism(WS/T 211-2001).Then blood and urine samples were collected in the surveyed people.Serum glutamate pyruvic transaminase(ALT)were detected by Enzyme-linked immunosorbent assay as the indicator of the impaired hepatic function.The microdosis albumen (mAlb)and acetylglucosaminidase(NAG)in urine were detected by end-point method and alkaline picric acid as the renal damage indicators.Results A total of 661 people investigated,of which 144 cases were arsenic poisoning patients.The rates of abnormal liver function were significant hisher in arsenic poisoning group[10.42% (15/144)]than that in control[5.22%(27/517)],and both wag significant[X2=5.107,P<0.05;OR=2.11,95%CI (1.09-4.08)].The geometric mean of mAlb/Ucr was 2.16 mg/g Cr in control,and 2.31 mg/g Cr in arsenic poisoning group,and both was not significant(t=-1.71,P>0.05).The geometric mean of NAG waft higher in arsenic poisoning group(2.43 U/g Cr)than that in the control(2.22 U/g Cr),and both was significant(t=-3.55, P<0.05).Conclusions The damage of the liver and renal function were related with endemic arsenism,and NAG is the early indicators suggesting impaired renal function due to endemic arsenism.
